RU(BPY)3 COVALENTLY DOPED SILICA NANOPARTICLES AS MULTICENTER TUNABLE STRUCTURES FOR ELECTROCHEMILUMINESCENCE AMPLIFICATION   Abstract The electrochemiluminescence (ECL) of doped silica nanoparticles (DSNPs), prepared by a reverse microemulsion method that leads to covalent incorporation of the Ru(bpy)3 2+, was investigated in acetonitrile and aqueous buffers. The emission was produced for the first time by cation-anion direct […]

NEW IODO-ACETAMIDO CYANINES FOR LABELING CYSTEINE THIOL RESIDUES. A STRATEGY FOR EVALUATING PLASMA PROTEINS AND THEIR OXIDO-REDOX STATUS   Abstract Two new iodoacetamide-substituted cyanines, C3NIASO3 and C5NIASO3, were synthesized starting from hemicyanine and were utilized for labeling plasma proteins. Specificity, sensitivity and feasibility for SH residues was tested utilizing an equimolar mixture of standard proteins […]
